Tesla ~~is at~~ may soon be at level 4 autonomous driving. It seems to me a taxi business could easily be made out of cars that can do that. Level 4 means they can drive fixed routes, that they know well and have mapped. When you think of a city and it's top 100 destinations, most taxi journeys are some combination of going between those. Going from the airport to downtown, and so on. Am I missing something? It seems if level 4 driving could handle those journeys, then perhaps it can handle most urban taxi journeys.
Even a taxi service that could just go to the top 50 destinations in a city from the airport, if rolled out across the world, could make serious money.
I'm trying to keep an open mind about these kind of efforts, though I have suspicions about some of them being green washing. However if solar power becomes ultra cheap in the 2030s, and can power efforts like this, it is possible they may make a significant difference.
